You should give more of an explanation on how to get Mimikyu, basically, here is my guide

1: Make sure you have a Pikachu, Heart Tail Pikachu works

2: Head to Gale Forest

3: Hunt for a Pikachu AT NIGHT (It may take a while, Pikachu has a 3% chance of appearing)

4: When you find a Pikachu, it'll turn into a Mimikyu, you'll obviously need to catch it
